Subtle Energy

Life energy permeates the universe, and because it is invisble to most people and not measurable by scientific instruments it is sometimes called 'subtle' energy. Subtle energy is recongnised in Eastern philosophy - in China, for example, it is called chi and in India prana. Traditional Chinese medicine and Indian yoga both work on this subtle energy, as do some Western complementary/alternative therapies. The subtle body is the energy field of a living organism, visible to some as the aura. It is also known as the energy, etheric, astral or dream body.
